Scroll batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

Scroll is an L2 smart contract platform for decentralized applications on Ethereum. Scroll was founded by Sandy Peng, Haichen Shen, and Ye Zhang and launched in 2023.

SCR tokenholders own and govern the protocol. Scroll's investors include Polychain, Qiming Venture Partners, etc.

# Scroll Contract deployers Methodology

## 1. Overview

The Scroll contract deployers metric measures the daily count of unique addresses that deployed smart contracts on the Scroll Layer 2 blockchain. This metric tracks developer activity and ecosystem growth by counting distinct deployer addresses per day. Each address is counted only once per day, regardless of how many contracts they deploy. This provides insight into the breadth of developer engagement on the Scroll network.

## 2. Data sources

The calculation uses the following raw data sources:

- **Scroll contract creation events**: Parsed contract deployment transactions from the Scroll blockchain containing deployer addresses, contract addresses, creation timestamps, and contract metadata
- **Scroll transaction traces**: Underlying transaction trace data that captures contract creation operations and their associated deployer information
- **Scroll block timestamp data**: Block-level timestamp information used to determine the exact timing of contract deployments

## 3. Step-by-step calculation

### Component A: Contract creation fact extraction
- **Purpose**: Extracts and deduplicates all contract creation events from Scroll blockchain data
- **Logic**: The system processes Scroll's contract creation data to extract key information including creation timestamps, deployer addresses, contract addresses, creation trace addresses, contract bytecode, and creator addresses. A deduplication step using DISTINCT ensures that duplicate contract creation records are removed, preventing double-counting of the same deployment event
- **Key fields**: `block_timestamp` (creation timestamp), `deployer_address` (address that deployed the contract), `account_address` (deployed contract address), `creation_trace_address`, `contract_bytecode`, `creator_address`

### Component B: Daily aggregation
- **Purpose**: Groups contract creations by day and counts unique deployers
- **Logic**: Contract creation timestamps are truncated to day-level boundaries to create daily time buckets. The data is then grouped by day along with standardized chain metadata. For each day, the system counts distinct deployer addresses to determine how many unique addresses deployed contracts. This approach ensures that an address deploying multiple contracts on the same day is counted only once
- **Key fields**: `timestamp` (day-level timestamp), `contract_deployers` (count of distinct deployer addresses), chain metadata fields including `chain_id` as 'scroll', `market_sector_id` as 'blockchains_l2', `business_segment_id` as 'blockchain'

### Final aggregation
- **Combining components**: The daily aggregated data flows through a metric finalization process that standardizes the output format and applies data quality measures
- **Currency conversion**: Not applicable for this count-based metric
- **Time aggregation**: Daily boundaries are created by truncating timestamps to day level, ensuring consistent 24-hour periods
- **Final calculation**: The final metric value represents the count of distinct deployer addresses per day on Scroll. The finalization macro applies a zero-fill strategy for missing data points and applies chain availability filters to ensure data quality and completeness. Each day's value represents the total number of unique addresses that deployed at least one contract on that specific day.
